ME221 Standalone Wire-In ECU.

Designed for fully sequential control of four cylinder engines, as well as forming an integral core to the range of ME221 based PnP ECUs, it’s a feature packed ECU, in a compact, reliable and affordable form factor.

With support for a range of OEM sensors and trigger patterns, as well as being versatile enough to offer flexibility where it’s needed – including often ‘expensive’ features such as Fully Sequential fuel control, Flex-Fuel, Closed Loop Boost & VVT as well as Windowed DSP Knock Control and core features such as programmable inputs, custom tune-able sensor tables and full 3D mapping, the ME221 really blurs the line between lower priced and higher featured engine management systems.

Essentially any port injection, four Cylinder engine, either turbocharged or normally aspirated can be ran semi or fully sequential with an array of Motorsport features to boot, all powered by the ME221 ECU.

This package includes the ME221 ECU, Wiring Loom (2.5 Meters, unterminated), RS232 Tuning Cable & Quick Start Sheet.

Note that as with all after-market engine management systems, basemaps are offered ‘as-is’, and dyno tuning is recommended to avoid damaging your engine. We have full engine dyno and rolling road facilities on site. Or alternatively we can point you in the direction of a tuning agent in your area.

1 x RS232 Communications Cable

1 x Quick Start Guide

Options

Coolant and air temperature sensors. The ME221 and MEITE software do offer the ability to calibrate the ECU to read any sensor, however by using the sensors on offer in this listing the standard calibration tables can be used - vastly simplifying the set-up process and saving considerable time. Both sensors are M12 x 1.5 thread. The additional coolant temperature sensor housing offers a quick and convenient method for installing directly into a radiator top hose and negates the need for tapping out existing holes in your cylinder head.

Crank Sensor. The ME221 ECU requires inputs from a crank position sensor. Therefore if your engine is not equipped with a sensor you will need to mount a suitable sensor such as this Ford Zetec type sensor, along with a trigger wheel on your front pulley. We list a range of universal trigger wheels in our shop.

Data Cable (FTDI USB-Serial Adaptor). Whilst the ECU comes with an RS232 cable many modern Laptops do not have such a connection. Therefore this adaptor will allow a USB port to be used for connectivity. This genuine FTDI cable is guaranteed to work with this ECU, unlike many cheaper alternatives that often suffer connectivity issues.

Basemaps

ALL ME221 and ME442 ECU's are shipped with a test map only. This is highly unlikely to run your engine and if it does it will not run it very well! A library of basemaps can be found here on the Motorsport Electronics Support Pages as well as a full suite of installation manuals. danST Engineering can also provide basemaps for a variety of engines developed on our in-house rolling road.

Coil Pack Compatibility

This ECU is intended for use with wasted spark Ford and Vauxhall coil packs. Other wasted spark coil packs may be compatible however please contact us before attempting to use alternatives to avoid potential damage to the ECU. The fitment of a Ford or Vauxhall coil pack (available in our shop) will guarantee compatibility and reliability.

Note: As with all after-market engine management systems (ECU’s) a dyno tuning is recommended to avoid damaging your engine and to get the most out of your engine.
